Improvements in the following is a fication.

My invention relates to gearing, and more especially tomeans for driving t at class of lighting devices or dynamos which are designed for lighting railway-cars and other vehicles and derive their power or motion from the axle of the vehicle; and my invention has for its primary object to provide improve and efficient means for driving at a uniform rate of speed always in the same direction regardless of the rate of speed or direction of motion of the car or vehicle.

' With theseends inview my invention consists in certain features of novelty in the construction, combination, and arrangement of parts by which the said objects and certain appearing are atthese shafts 12 13 are mounted in boxes 14 15, respectively, sliding in suitable guides 16 and connected together by a spring 17 or ble of drawing Car-Axle Gearing, of which full, clear, and exact speciof the armature-s arranged between the shafts 12 13 and in line therewith, is provi ed with a pinion or gear 20, engaging with pinions 19 and connected with the shaft 2 by means of a spline 21, so as tained, all as fully described with reference to to be capable of sliding longitudinally of the the accompanying drawings and more parshaft 2 while turning it. All three of the ticularly pointed out in the claims. v shafts 2, 12, and 13 pass'through a crossar In the said drawings, Figure 1 is a front 22, arranged just above the pinions 19 20 and elevation of my improved apparatus. Fi 2 held from moving longitudinally on the is a side elevation thereof. ig. 3 is a p an shafts by collars or flanges 23, secured to section taken on the line 3 3, Fig.2, the large shafts 12 13, while just below the pinions disk being shown in elevation. Fig. 4 is a 19 20 is a similar cross-bar 24, through which plan section, on an enlarged scale, taken on the three shafts pass, and sleeved on the the line 4 4, Fig. 1. Fig. 5-is a detail section shafts 12 13 below thecross-bar 24 are coiled taken on the line 5 5, Fig. 3. Fig. 6 is an ensprings 25., which take their bearing between larged detailed view, partly in ver Ycalseetion the bar 24 and the supports 16, whereby they 0 and partly broken away, of the power-transexert a tendency to push the shafts 12 13, mitting mechanism; and Fig. 7 is a diagramwith their pinions 19 and other. connecte M matic view illustrating the direction of rotaarts and the pinion 20, outwardly away tion of the various shafts and rotary memfrom the center of the disk 9, thereby increasbers. ing the speed of rotation of the arinature- 5 1 represents the dynamo, and 2 the armashaft. ture-shaft thereof, which is mounted in any The extremities of the shafts 12 i3 opposuitable bearings 3 4, and 5 is a 'countersite those carrying the wheels 10 11 are rotashaft which may be driven from the'axle of tably attached to a sleeve 26, which slides the car or vehicle (notshown) by belt 6 and loosely upon the shaft 2 This attachment ioc pulley 7' or by any other suitable means, and, may be conveniently effected by means of a indeed, so far as the purposes of this invencross-bar 27, through the ends of which the tion are concerned the shaft 5 may be reshafts 12 13 ass and are provided on oppoarded as the axle itself. In the example of site sides of the cross-bar with collars 28 29, the invention shown in the drawings the the sleeve 26 being similarly passed through io shaft 5 is supported by suitable bearings 8, and upon this shaft is secured a friction-disk 9, against opposite sides 0 the cross-bar 27 and provided on o posite sides thereof with collars 3O 31, so t iat the sleeve 26 will move longitudinally of the which engage l shaft 2 during the reciprocating motion of the shafts 12 13 while turning with relation to the shafts 12 13. This sleeve is keyed to shaft 2 by spline 21 and operatively connected to a centrifu al overnor,. preferably prising a air'o ba ls "32, connected by links 33 with t e sleeve 26 and by links 34 with a collar 36, ri idly fixed to the'shaft 2, so that as the speed of the friction-disk 9 increases the balls 32 will swing outwardly and compress the springs 25 in the manner shown in Fig. 1, thereb forcing the friction -wheels 11 nearer to tii 9 and d ing the s eed disk 9 inwardly, as shown in dotted lines in Fig. 1, and the wheels 10 11 will be forced outwardly toward the perimeter of disk 9, thereby increasing or maintaining the speed of shaft 2, it being understood that the sleeve 26 imbar 27 and collars 28 29, while the springs impart their motion to the sleeve 26 and to bar 24 and collars 23.

In order that rotation of the disk 9 in either direction will cause rotation of the shaft 2 always in the i wheels are so one will revolve its shaft when the disk 9 r'otates in one direction and the other will revolve its shaft when said disk rotates-in the opposite direction. This may be conveniently effected by making the wheels 10 11 loose on'their shafts and providing them with pawl-and-ratchet connection with the shafts.

or example, to each of the shafts 12 13 is secured a hub 37 b other suitable device, which 1s provided on one side with a pawl 39, normally pressed outwardly by a sprin with a tooth 41, formed on each of t e wheels 10 11. hown in the drawings, the hub substantially 41 is formed in the inner edge of the wheel adjacent to the hub, so as to engage with the pawl 39 when the wheel revolves in one direction, but to slip past the awl without re- VolV1ng the hub 37 when t e wheel revolves in t e opposite direction. These wheels 10 on opposite sides of the mug. v

In Fig. 71 have shown dia rammatically lllr' direction of rotation of t e shafts and ozhvr rotary members resulting from either aim-nun of rotation onthe car-axle. In this lip-urizlnarrows at indicate the direction of nuarion resulting frointhe rotation of the into engagement axis 5 and driving-disk 9 in a direction toward the right, and the arrows b illustrate the opposite direction of rotation. I

aving thus described niy invention, what claim as new therein, and desire to secure by Letters Patent, is-
